Abstract

An ignition system having improved reliability for a gas turbine combustor is disclosed. The ignition system comprises an outer housing having at least one fuel passage and an electrode extending therethrough forming a generally annular passage for cooling air to pass to a mixing chamber. Fuel and air mix in the mixing chamber to form a combustible mixture that is ignited by the electrode. The outer housing further comprises a plurality of air swirl holes to effectively cool the walls of the mixing chamber as well as to provide improved flame stability.

Description

TECHNICAL FIELD

[0001] The present invention generally relates to gas turbine engines and more specifically to an ignition system that provides an improved starting reliability for a combustion system of the gas turbine engine. BACKGROUND OF THE INVENTION

[0002] Combustion within gas turbine engines is typically initiated by an ignition system having a heating source. Historically, two different types of igniters have been used, one located within the combustion chamber and the other located outside of the combustion chamber. It is preferred from a durability point of view to have the ignition system located outside of the combustion chamber such that it is not directly in contact with the hot combustion gases that can reduce component life. However, this arrangement requires the ignition system to be extremely reliable given its proximity to the combustible mixture. Because of this reliability issue, a compromise of configurations evolved resulting in a retractable igniter. Once ig...
